U+208B Subscript Minus

U+208B wurde in Version 1.1 in 1993 zu Unicode hinzugefügt. Er gehört zum Block U+2070 bis U+209F Superscripts and Subscripts in der U+0000 bis U+FFFF Basic Multilingual Plane.

Dieses Zeichen ist ein Math Symbol und wird allgemein verwendet, das heißt, in keiner speziellen Schrift.

Das Zeichen ist eine tiefgestellt Variante des Zeichens Minus Sign. Es hat keine zugewiesene Weite in ostasiatischen Texten. In bidirektionalem Text wird es als europäischer Nummerntrenner von links nach rechts geschrieben. Bei einem Richtungswechsel wird es nicht gespiegelt. Das Wort, das U+208B mit ähnlichen Zeichen bildet, verbietet in sich Zeilenumbrüche.

Die Wikipedia hat die folgende Information zu diesem Codepunkt:

Unicode has subscripted and superscripted versions of a number of characters including a full set of Arabic numerals. These characters allow any polynomial, chemical and certain other equations to be represented in plain text without using any form of markup like HTML or TeX.
The World Wide Web Consortium and the Unicode Consortium have made recommendations on the choice between using markup and using superscript and subscript characters:

When used in mathematical context (MathML) it is recommended to consistently use style markup for superscripts and subscripts […] However, when super and sub-scripts are to reflect semantic distinctions, it is easier to work with these meanings encoded in text rather than markup, for example, in phonetic or phonemic transcription.
